Yes, the sawdust from most types of wood is safe for composting. Sincesawdust comes from trees, the material is a natural source of carbon-based, orbrown, ingredients to add to your composting system.
Sawdust makes a perfect addition because it’s airy nature helps keep thetexture of the compost loose yet still wicks up excess liquids when necessary.Both of these tendencies help keep the microbes feeding hungrily within the pile, which increases the decomposition process.
I don’t advise using large amounts of sawdust from treated wood in asingle batch of compost, as the chemical residues can remain high in thefinished compost and possibly kill your garden plants.
Adding in smaller amounts per batch allows any harmful chemicals toleach out or break down without detracting from the safety of the completedcompost.
Are you working on home renovations orwoodworking DIYs and wonder if you can add pine shavings in compost safely?Yes, you can compost sawdust and wood shavings when you follow theguidelines in this article. Inside, I detail if sawdust or wood shavings aregood for compost, pros and cons, and the best way to compost sawdust and woodchips.
So, don’t toss that bothersome wood waste. Put it to good use makingrich compost for your garden
Sawdust brings both good and bad aspects to your compost, such as:
Pros:
· Provides a carbon ingredient
· Is already broken down into tiny particles
· Acts as a sponge to wick up moisture fromoverly wet material
· Improves the texture of finished compost
· Environmentally-friendly way to discard woodwaste
· Creates a barrier that holds in odors anddeters pests
Cons:
· Must take extra care when adding sawdust fromchemically-treated wood
· Sawdust pulls a lot of nitrogen from thecompost during the initial breakdown
Step 1. Think of sawdust as a brown compost ingredient similar to shredded dry leaves. A ratio of 4:1 is about right when mixing it with nitrogen-rich “green” ingredients. Add in the appropriate amount of sawdust to your composter, using a bit more if the other ingredients are very wet, or less if the material seems dry.
Step 2. Before mixing the sawdust into yourcompost, spray it with water until it absorbs a fair amount of liquid.
Wetting the sawdust will keep it from blowing away, as well as providecritical moisture inside the compost, which microbes need to thrive.
Step 3. Turn and aerate the compost often. Sawdust texture is fine, which means it can compact down fairly quickly and cut off the air supply inside the pile, which will cool it down and retard the decomposition process.
Turning the pile with a garden fork or rolling a compost tumbler every couple of days is the best way to keep the sawdust and other ingredients breaking down as fast as possible.
Step 4. If you have plenty of sawdust and worryabout pests, you can add a layer two inches thick over the top to seal inodors. In colder temperatures, a thick layer of sawdust is also ideal forholding in heat.
Doing your part for your garden and the environment by compostingsawdust and wood shavings is a smart way to dispose of the waste thataccumulates when working on projects around the home.
I hope this guide shows you that incorporating sawdust and wood chipsinto your composting system is not difficult, but rather a safe way to recyclewoodworking waste into helpful compost that makes your garden grow
